should also generally be fenced and furnished with a gate 

 which can be locked. The arrangement of the wood is done in 

 a similar way to that in river-depots, which will be now 

 described.

2. Riccr-depots. 



A large number of depots are used for storing wood after 

 transport by water, and different arrangements are then required 

 from those described under land 

 transport, especially after the 

 wood has been floated. 



The necessary characteristics 

 of a good river-depot are: — im- 

 mediate proximity to the float- 

 ing-channel ; a site thoroughly 

 exposed to air and wind ; 

 the soil formed of sand, gravel 

 or boulders to a depth of at 

 least half a meter [Ih feet) — 

 otherwise it should be paved 

 with large stones ; elevation of 

 a few yards above the highest 

 flood-level of the stream, or in 

 case the depot is so arranged 

 that the wood lands itself, a 

 sufficient fall in the different 

 basins of the depot, which are 

 separated by sluice-gates. In 

 many cases it is also necessary 

 to include protective works 

 against floods, which will l)e 

 described further on. 



Wherever only a little wood is floated and labour is plentiful, 

 a bank of the stream above the boom, if otherwise suitable, is 

 generally selected on which the wood is landed. As all the wood 

 must then be dragged from the stream, and many men thus 

 simultaneously employed, the depot should extend for some 

 distance along the river-bank, and its breadth be reduced to a 



chtcsgaden.
